Need Help Quickly

i have a work colleague, who is leaving us today for a new job (researching the good death!!!) so obviopusley her leavers cake is going to have to be a coffin. I have to have it ready in an hour and a half, but i just can't think of anything to write on the cake

im looking for something that says goodbye and goodluck with a hint of rip or death (in a commical way of course)
